Feature Request: Hide a parameter from the annotation

还没有人认领这个 Issue。

I have a table with a metatable assigned to it to implement inheritance. The metatable's `__index` metamethod intercepts a call to a function on the original table and gets the actual function from the "parent" table and then injects another parameter into the function call.

For example, the user would call the function like this: `tbl:Execute("hello", "world")` and the function would be implemented like this:

```lua
function ParentTable:Execute(data, hello, world)
-- data is a special parameter controlled by the metatable and is given a table value
-- hello is assigned "hello" and world is assigned "world"
end
```

The problem with this is that VS Code and LuaLS warns the user that they didn't provide a value to `data`. I have to use `@overload` to every single method to say you can call this method with just "hello" and "world" arguments provided.

I want to be able to tell LuaLS to completely hide/ignore the `data` parameter and pretend it doesn't exist; essentially moving all other parameter indexes down by 1 to fill the empty spot, so "hello" is recognized as parameter 1 and "world" as parameter 2.

首先追踪 LuaLS 如何处理函数参数注解、@overload 声明，以及通过元表的 __index 元方法拦截的调用。完成的标准是：LuaLS 能够隐藏注入的数据参数，调整可见参数的位置，并在调用方只提供 hello 和 world 时停止发出警告。
